在B站上发现了资源，就看了一下。演示的动画很吸引人。是用心之作。
一是内容编排好。正如其简介所说，这些资源不是用来教大家解题的，而是加深对概念的理解(Rather than focusing on problem solving, the objective is to give insight into the concepts on which the rules of mathematics are based.)。这些内容的讲法值得我们的大学、中学、小学老师来学习借鉴。
二是内容有味道。内容不是呆板地讲，或者板起面孔讲，不生硬。比如讲到负数的产生，娓娓道来，还配合一点历史发展。很有趣。科学不就是这样一点点发展起来的吗？由不被认可，到流行起来。

二是对补充专业的英语有好处。大学英语过了六级，在一些简单的数学表达面前 还是有些捉襟见肘。此外，一些术语应该不常用，竟然存在一直读错的情况，这也是得以纠正的好机会，比如在看了一些基础的视频后，我就发现自己一直把integer读错。也熟悉了一些数学的表达。比如幂次的读法。
Why U animated videos are designed for mathematics courses on the K-12 and college levels, and as a resource for informal independent study. Rather than focusing on problem solving, the objective is to give insight into the concepts on which the rules of mathematics are based.
Why U creators are currently working on the series of animated lectures entitled "Algebra". This series examines the concepts on which Algebra, as well as higher mathematics, is based. The goal of these lectures is to explore these fundamental concepts in greater depth than possible in most high-school and college-level algebra courses.
Why U videos are conceived and written by Steve Goldman and animated by Mark Rodriguez. Why U is a 501(c)3 non-profit organization funded by the Goldman Charitable Foundation.
